I've some tested with --prefix=/@unixroot/usr. Unfortunately, however,
it did not work as expected.

Because /@unixroot notation is specific to kLIBC, and many tools not
built with kLIBC exist. Those tools do not understand /@unixroot. After
all, to use /@unixroot in autoconf/automake is not adequate.
